Be it known that I, GEORGE A. FREDEN- nUuen, a citizen of the United States, residing in the city of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful lmprovements in Thread-Dressing Machines, of which the following is a specification.

My invention relates to tlu'ead-dressing machines, and more especially to the brushes and tlu'ezul-ironers thereof; and it consists of the novel construction of the several parts, as hereinafter described,and specifically set forth in the claims.

My present invention relates to improvements on certain parts of the threzu'l-dressing machine described and claimed in Letters `Patent of the United States, No. 012,786, issued to me June 1T, 1902.

Figure 1 is a front elevation of my improved tlu'ead-dressing machine. Fig. 2 is a central longitudinal sectional view taken on line ,1' r of Fig. 1. Fig. 3 is a similar sectional view taken on line j/ y of Fig. 1. Fig. 1 is an enlarged cross-sectional view of the machine, taken on line .1 .1' of Fig. 1. Fig. 5 is aperspective view of a modified form of a threadironer. Fig. 6 is a central longitudinal sectional view of the driving end portion of the brush.

Like numerals indicate like parts.

ln the drawings, 1 1 represent the standards forming a part of the framework of the machine. Steam enters through the pipe 2, which at intervals is provided with elbows and T-couplings, of which five are shown at the right of Fig. 1, (designated as s1, 5, 6, and 7, respectively.) The pipe 2 is made up of sections united by the T-couplings 3, 4, 5, and 6. '.ll ie steam passes from the machine through the pipe made up of sections, which are united by the T-couplings 9, 10, 11, and 12. A pipe 13 extends horizontally from the elbow 7 to the elbow 11. A pipe 15 extends from the T-coupling 6 to the T-coupling 12. A pipe 16 extends from the T-coupling 5 to the T- coupling' 11. A pipe 1T extends from the T- coupling e1 to the T-coupling 10. A pipe 18 extends from the T-coupling 3 to the T-coupling 9. A stationary ironer 19 is a tube having integral collars 20 20 and reduced tubula 1' ends 21th These collars 20 abut the inner sides of the standards 1 1 of the frame of the machine, and so prevent endwise movements of said tube 19, and the reduced tubular ends '21 21 pass through bearings made therefor in the standards 1 1. ln like manner the stationary ironer 21 is a tube having integral collars 2Q 2Q and reduced ends 23 '23. 'lhe collars Q2 are iu abutment with the stainlards l l of the frame and prevent endwise movements of the tube "2l, and the reduced ends 23 23 of thel tube 21 pass through bearings made therefor in said standards 1 1.

The stationary ironer 21 surrounds concentrically the steam-pipe 15, which pipe is of such diameter' as to lit snugly in the reduced ends Q3 23 of the tubular ironer 2l, and there is le'ft an annular space between the exterior surface of the pipe 115 and the interior surface of the tubular ironer 21, as fully illustrated in Fig. Q. 'l`heironer21 is heated by radiations from the steam-pipe 15 in said annular space. In like manner the steam-pipe 13 passes through the stationary ironer 19. On both the stationary ironers 19 and 2l are a series of circumferential grooves 21.

The stationary ironer '21 is fastened in position by the plates .25 bolted at 2G 26 to the standards 1 l. Set-screws .T '27, through the plates 25 25, have their inner ends bear against the reduced enils 23 23 of the ironer 21, and thus the ironer 2l is held from rotation upon the machine-frame. ln like manuel' the ironer 19 is held fixed in position by plates, bolts, and set-screws, as illustrated in Fig. 1.

The ironer 28 is a tube. (Shown in elevation in Fig. 1 and in central horizontal section in Fig. 3.) lt has a series of circumferential grooves 29. lollars 30 30', iuteg'ral with the ironer 2S, are. provided, beyond which the tube 28 is reduced in diameter to form annular flanges 31 31, which are beveled to receive balls 3Q. The bore of these reduced ends is of such diameter as to loosely receive the steam-pipe 16, which passes through the tubular ironer '28 coiicentrically. Sleeves 33 33 are slidably mounted on the pipe 16 and have annular beveled edges to receive said balls. These sleeves 33 33 are held in proper IOO position with relation to the annular flanges 31 31 of the ironer 28 to form circular V- shaped grooves for said balls by means of collars 34 34, which are fastened in place on the pipe 16 by set-screws 35 35. On one end of the ironer 28 is a gear 36, which abuts the collar 30 and is keyed or otherwise fastened to the ironer 28, so as to rotate the same.

The ends of the steam-pipe 16 pass through bearings 37 37 in the standards 1 1 and are held fast in position by the plates 38 38, bolted at 39 39 to the standards 1 1, and by the setscrews 40 40, which pass through the plates 38 38 and bear against said pipe 16.

On one of the standards 1 is a tubular bearing 41, in which is fastened a short shaft 42 by means of a set-screw 43. On said shaft 42 is loosely mounted a driving-gear 44, which meshes with the gear 36 of the rotating ironer 28. A collar 45 on the shaft 42 is fastened by a set-screw 46 and holds the gear 44 from outward displacement. The gear 44 has a long hub, whose inner end abuts the surface of a boss 47 on the standard 1, as shown in Fig. 3. A pulley 48 is keyed or otherwise fastened to the hub of the gear 44. A belt 49 passes over the pulley 48 to turn the same, and thus the driving-gear 44 is rotated. This pulley 48 is driven by the belt 49, which also passes over the pulley 50 on the driving-shaft 51, Fig. 4.

The pipe 17 extending from the T-coupling 4 to the T-coupling 10, is fastened by bearings, plates, and set-screws in the same manner that the pipe 16 is and is surrounded by a rotary ironer 52, in all respects like the rotary ironer 28 and similarly mounted and furnished with ball-bearings, &c. The rotary ironer 52 has a gear 53 and circumferential grooves 54. The gear 53 meshes with the driving-gear 55, which is mounted on the shaft 56, that is fixed to the machine-frame in a manner similar to shaft 42. On the hub of the gear 55 is made fast a pulley 57. A belt 58 from the driving-pulley 50 of the shaft 51 turns the pulley 57 of the gear 55.

The pipe 18, extending from the T-coupling 3 to the T-coupling 9, is fastened by bearings, plates, and set-screws in the same manner as the pipe 16 and is surrounded by the rotary tubular brush 59, which is provided with the bristles 60. The construction of this brush 59 is substantially the same as that shown in United States Letters Patent No. 746,946, issued to me December 15, 1903. This brush 59 is made fast upon a tubular shaft 18, which loosely surrounds the steam-pipe 18, as seen in Fig. 4, and said shaft has its ends made sol-id, so as to form hubs, as shown, at 18b in Fig. 6, and these hubs loosely surround said pipe 18 and have their interior surfaces beveled inwardly, as seen in said figure A sleeve 331 on the pipe 18 is made to enter each end of the tubular shaft 18u and is beveled inwardly, so that between the hubs 18" of said tubular shaft and sleeves 33aare formed V -shaped channels, in which balls 32L are mounted. The brush 59 is prevented from endwise movement on the steam-pipe 18 by collars which abut the sleeves 33, as shown at 34 in Fig. 6, and these collars are fastened in place upon the pipe 18 by set-screws in the same manner as for the rotary ironers 28 and 52. A gear 61 is made fast upon one hub of the tubular shaft 18u and meshes with the driving-gear 62 on shaft 63. Said driving-gear 62 is loosely mounted on a short shaft 63, and on the hub of the gear 62 is keyed a pulley 64. The shaft 63 is fiXedly secured to a standard 1 and has a collar fastened by a set-screw to hold the gear 62 from outward displacement in the same manner as for the driving-gears 44 55 of the rotary ironers. A belt 65 from the driving-pulley 50 on the shaft 51 rotates the pulley 64, mounted on the hub of the gear 62. By the crossing of the belt 58, as shown in Fig. 4, the gear 55 is driven in a direction opposite to that of the rotation of the gears 44 and 62.

On portions 66 of the frame of the machine rods or bars 67 are adjustably mounted and held in position by the set-screws 68. Peripherally-grooved rollers 69 are mounted on the outer ends of said rods or bars 67, respectively. Said rods or bars 67, with their rollers 69, constitute the means for regulating the desired tension of the thread upon the brush and ironers.'

A bracket 70 is mounted on a portion 71 of the machine-frame by bolts 72. A pulley 73 rotates a shaft which is mounted in said bracket and is driven by a belt 74. A gear 75 rotates with said shaft and meshes with a gear 76, which carries a twisting-head 77. Each twisting-head 77 has thread-guides 78 and 79.

Having thus described the parts of my improved thread-dressing machine, I will proceed to explain its operation. The thread 80 having' passed from Vthe reel and having been carried through the trough of sizing' liquid (not shown, because they do not constitute any part of my present invention, but are shown in my said priorpatent of June 17, 1902) goes up through the thread-guide 79, the twistinghead 77, and the th read-guide 78 and is twisted by the gearing and pulley 76 75 73, driven by the belt 74. The thread 8O so saturated and twisted first comes into contact with the bristles 60 of the cylindrical brush 59, and the projectingiibers of the thread are properly laid by the brush operation. The steam enters the pipe 2, passes thence through the pipes 18, 17, 16, 15, and 13, and thence passes out through the pipe 8. Between said pipes 13, 15, 16, 17, and 18 and the tubes 19, 21, 28, 52, and 59, which surround said pipes, respectively, are annular spaces, as shown in Figs. 2, 3, and 4, so that the radiation of heat from said pipes through said annular spaces heats said tubes. The

steam heat in the c vlindrical brush and brushshafting causes the rapid drying of the saturated thread. The thread 8() next passes up and behind the lower tension-roller 69 in the groove thereof and thence behind the rotary ironer in the groove 51 thereof, thence in front of the rotary ironer 28 in the g'roove 29.

thereof, thence behind the stationary ironer .21 in the g'roove 24 thereof', thence in front of the stationary ironer 19 in the groove 2% thereof, thence behind the upper tensionroller (5) in the groove thereof, and thence is carried to the spools (not shown) and woune thereon, as usual, the draft on the thread being caused by the winding mechanism. By this travel of the thread 8O over the ironers in the grooves thereof the thread is ironed and polished. the rate of rotation of the rotary ironers 28 and 52 being' more rapid than the rate of travel of the thread which passes over them. These peripheral g'rooves in the irouers are half-round. and therefore as the thread passes alternately behind and in front of' these ironers one after the other in the series the thread is ironed all around and equally. The tension devices cause the thread el) to be drawn tig'htly in this ironing operation. rlbe lower ironers 52 and 28. which first operate on the thread 80 to smooth and polish it. are rotary and turn in the directions indicated by the arrows r/ and but the ironers 2f and 19 do not rotate, but are stationary, and therefore are adapted to impart the final finish to the thread. The stationary ironers 1%) '21 from time to time may be moved in order to present a different peripheral surface to the thread as the latter passes over them. This done by loosening' the set-screws, slightly turning' the ironers 19 21, and then tightening the set-screws again. 1n this manner the uneven wear of the surface of said irouers is prevented.

ln Fig'. 5 l show a modification of the ironers in which the circumferential grooves are omitted and the surface is perfectly smooth and cyliinlrical.
